Fuel dilution is not a function of the oil viscosity - it's a function of the ECU tune for engine fueling & combustion and the level of the rings blowing by combustion gasses. Only way to help mitigate the reduction of the oil viscosity from fuel dilution is to: a) use a thicker hot viscosity rating and/or b) change the oil more often.
I'm planning a UOA at 4k, to see if the EP does better than the AFE, if not better will change intervals to 4k, strangely the dilution in my 19 Civic Touring Coupe was always in the .5% or less with 5k intervals and AFE, the CRV, which is essentially the same engine with a bit more boost is tougher on oil. Perhaps more boost, more dilution. I know the tune is different because it's a heavier vehicle and, not surprisingly, uses a bit more fuel
